A simple algorithm for calculating the maximum value of a given array is to initialize a maximum variable with the first element of array, then iterate through the array elements while replacing the maximum value with the larger number whenever found. After the loop is finished, the maximum value is the maximum number of the array.

def find_maximum(arr):
    max_val = arr[0]
    for elem in arr:
        if elem > max_val:
            max_val = elem
    return max_val
